Details:

The command "probe -u" always uses small letters in its  output. But when
applied to an ntfs partition it  should  use capital letters. Otherwise it
cannot be used in the "root=UUID=..." argument of the "linux" command.  

Example:

Wubi is installed on some ntfs partition in the file /ubuntu/disks/root.disk

The following sequence of commands from the Grub shell should boot Wubi:

set path=/ubuntu/disks/root/disk
search -f --set ${path}
probe -u  --set=Host_UUID ${root}
loopback loop0 $path
set root=(loop0)
linux /vmlinuz root=UUID=${Host_UUID} loop=${path} ro
initrd initrd.img
boot

But it fails with an error message like

Alert  /dev/disk/bu-uuid/735be1630b5aa140 does not exit.

This happens  since "probe -u  --set=Host_UUID ${root}" set $Host_UUID equal
to "735be1630b5aa140" rather than "735BE1630B5AA40" 

I'm sure only very few people will run into this bug. But it should be easy
to fix.
